Ingredients

2 tablespoons unsalted butter

2 tablespoons extra-virgin olive oil

1 medium red onion, finely chopped

1/2 lb chicken livers, trimmed and patted dry

1/4 to 1/2 teaspoon hot red-pepper flakes

3 tablespoon capers, rinsed and coarsely chopped

1/2 cup sweet (red) vermouth

1 cup chopped parsley

1 sourdough baguette, thinly sliced and toasted

1 lemon wedge

Preparation

Heat butter and oil in a 12-inch heavy skillet over medium heat until foam subsides, then cook onion, stirring occasionally, until softened, about 3 minutes. Add livers and cook over medium-high heat until undersides are browned, about 3 minutes. Turn livers over and add red-pepper flakes, capers, and 1 tsp salt. Cook until livers are just cooked through, 5 to 7 minutes more. Increase heat to high and add vermouth. Boil, stirring, until slightly thickened and glossy, about 3 minutes. Transfer livers with a slotted spoon to a cutting board, then transfer sauce to a bowl. * Coarsely chop livers and add to sauce. Season with salt and pepper and gently stir in parsley. Spoon onto toasts and squeeze a little lemon juice over each.

COOKS’ NOTES:

Liver mixture, without parsley, can be made 1 day ahead and chilled. Reheat, then stir in parsley, before spreading on toasts.
